Discovery to Launch Channel on Environmentally Conscious Living

SILVER SPRING, April 5: Discovery
Communications is rebranding its Discovery Home Channel as Discovery
PlanetGreen, which will feature content on environmentally conscious
lifestyles, and has set aside $50 million to invest in eco-friendly original
content for all of its 14 U.S. networks.

Announcing the multiplatform
Discovery PlanetGreen initiative today at Discovery’s Upfront presentation in
New York, chief executive David Zaslav commented: "The Earth has been
central to Discovery since John Hendricks first chose the planet to represent
our brand. The goal of Discovery PlanetGreen is to use Discovery's worldwide
credibility to be the most comprehensive and trusted global resource for
celebrating, preserving and protecting the planet," said Zaslav. "The
enormous viewer response to Planet Earth
demonstrates the interest and passion for more information about our wondrous
planet. Discovery PlanetGreen aims to be the number-one media destination for
this growing consumer segment."

The Discovery PlanetGreen channel is expected to debut in
more than 50 million homes in 2008. It aims to provide entertaining, authentic
and quality information for such categories as eco-design, organic food and
green architecture. In addition to the channel, an accompanying website will
provide resources, advice and original content like the short-form series Go
Green. Leading Discovery PlanetGreen will
be Eileen O'Neill, former GM of the Discovery Health Channel.

Discovery is also investing $50 million to create content
focused on sustainable development, conservation, organic lifestyles and
healthy living across the company's portfolio of 14 U.S. television networks.
The priority will be on core genres such as science and technology,
transportation and ecotourism, engineering, home greening and organic living.
The first major content initiative will be Discovery Channel's new series, Ten
Ways To Save The Planet. Premiering in the
third quarter of 2008, the series aims to find solutions to the planet's most
serious environmental threats, and will work with the world's leading
eco-scientists to test ideas, including wrapping glaciers in thermal blankets
to stop their melting, dropping thousands of saplings from planes to provide
mass reforestation, and painting entire towns white to reflect the sun.

The Discovery PlanetGreen campaign also includes scientific
exploration: beginning this year, explorer and wilderness educator Josh
Bernstein will lead an annual scientific journey, funded by Discovery
Communications and comprised of educators, students and sponsors, to the
planet's most endangered locations.

In addition, the company is creating an advisory board made
up of preeminent scientists, researchers, innovators and environmental leaders.
The Discovery PlanetGreen Advisory Board will advise and support the company's
program development, partnership outreach and corporate innovation activities.
